PF: Axs is a raise from MP? I think SHC says it's a fold but well, I think it's fine anyway.

Flop: I think when you get raised by the fish here he always has you beat, that is to say, a better ace at least. I would therefor much prefer to just call the raise, and try to hit the flush.

Basically when you go all in here against a better ace only (not counting sets or 2pairs), you're in with a coinflip where you're a slight underdog (48 vs 52), so I don't think this is a profitable move unless you *often* can put villain on something worse than a top pair (not likely even fish will push 160bb with worse).
